Question

我正在使用jackrabbit服务器，我们遇到了在群集中运行多个存储库的问题。问题是文件插入的文件夹结构路径有时发生在第一个repo上，而文件插入第二个（在两个服务器同步之前）。我为此设计的解决方案是更改Jackrabbit源代码，如果文件路径DOSENT存在则为文件创建文件夹路径而不是仅仅丢弃409 CONFLICT错误以下是JackRabbit web-Dav

中AbstractWebDavServlet的变化

    protected void doPut(WebdavRequest request, WebdavResponse response,
                     DavResource resource) throws IOException, DavException {

    DavResource parentResource = resource.getCollection();
    if (parentResource == null || !parentResource.exists()) {
        if(!parentResource.exists()) {
            try {
                createFolder((Session)request.getSession(), parentResource.getLocator().getPrefix(),parentResource.getLocator().getHref(true));
            }catch(Exception e) {
                throw new IOException();
            }

        }
        // parent does not exist
        response.sendError(DavServletResponse.SC_CONFLICT);
        return;
    }

    int status;
    // test if resource already exists
    if (resource.exists()) {
        status = DavServletResponse.SC_NO_CONTENT;
    } else {
        status = DavServletResponse.SC_CREATED;
    }

    parentResource.addMember(resource, getInputContext(request, request.getInputStream()));
    response.setStatus(status);
}
private String[] getFolders(String desUrl) throws Exception {
    if (null == desUrl || desUrl.length() == 0)
        return null;

    String[] folder = desUrl.split("/");
    String[] folders = new String[folder.length];
    for (int i = 0; i < folder.length; i++) {
        if (i == 0)
            folders[i] = folder[i];
        else
            folders[i] = folders[i - 1] + "/" + folder[i];
    }
    return folders;
}

public void createFolder(Session session123,String prefix,String href) throws Exception {
    String[] folders = /*this.getFolders(href.substring(prefix.length(),href.length()))*/href.substring(prefix.length()+1,href.length()-1).split("/");
    if (null != folders) {
        String davFolder = "";
        int length = folders.length;
        //Session session123 = ((JcrDavSession)session).getRepositorySession();
        Node rootNode=session123.getRootNode();
        for (int i = 0; i < length; i++) {
            if(!rootNode.hasNode(folders[i]))
                IOUtil.mkDirs(rootNode, folders[i], NodeType.NT_UNSTRUCTURED);
            else
                rootNode.getNode(folders[i]);
        }

    }
}

...

现在我处于一个噩梦般的情况，试图找到一种方法来获得会话。上面的方法让jcr会话有效。

请帮助

您是否尝试使用与doMkCol()相同的技术：

parentResource.addMember(resource, getInputContext(request, null));

看看JackRabbit中的Jackrabbit AbstractWebDavServlet中是否存在该节点
